This is a test to validate that we're not adjusting up i_size before we have the appropriate file extents on disk. We had a problem where i_size would be adjusted up without a contiguous range of file extents, which isn't ok without a special option enabled.

# Validate that without no-holes we do not get an i_size that is after a gap in

# the file extents on disk. This is fixed by the following patches
|
|
#
|
|
# btrfs: use the file extent tree infrastructure
|
|
# btrfs: replace all uses of btrfs_ordered_update_i_size
